2. A second advantage of plasticizers is the possibility of considerable savings in cement mortar. Adding plasticizers to the concrete solution can save on the amount of cement mortar. If you compare a solution prepared without adding plasticizers and with them, the amount of cement used in the second case will be 14-17% less. 3.

Krystol Mortar Admixture™ (KMA) Product Code:K-309 Description Krystol Mortar Admixture (KMA) is a hydrophilic crystalline admixture used to provide long-term protection of masonry mortars and concrete masonry units against water and waterborne contaminants by reducing permeability and absorption of the mortar. KMA simplifies installation by removing the need for surface applied sealers and ...
ACRY-LOK is a high-solid, acrylic polymer latex admixture and bonding agent. This milky white liquid is non-yellowing in Portland cement mortars and concrete. When used as an admixture, ACRY-LOK provides increased abrasion, impact and crack resistance, flexural strength, and freeze/thaw tolerance. Permeability is also reduced, providing added protection from chloride intrusion and scaling.
